Our experience in the treatment of intrathoracic and intraspinal hourglass neurogenic neoplasms

: The authors describe their experience in the treatment of dumbbell neurogenic tumours, intrathoracic and intraspinal, with particular reference to clinical presentation, diagnostic for imaging, anatomo-pathological classification and surgical treatment, comparing their clinical cases (9) with the international literature, accurately reviewed. The authors think that the best surgical treatment is the combined approach, in only one stage, of thoracic surgeon and neurosurgeon by hemilaminectomy and extended costotrasversectomy, reserving hemilaminectomy and thoracotomy only for the tumours with big dimension of intrathoracic portion.
